Abstract

The present disclosure relates to a vascular closure device adapted for use in closing a puncture in a blood vessel after e.g. a percutaneous interventional procedure. The disclosure also relates to a method for vascular closure using such a vascular closure device.

Claims

1. A vascular closure device for treating a passage in a blood vessel by closing a passage through tissue proximate to the blood vessel, the vascular closure device comprising:

an elongated housing having a proximal end, a distal end, and a distal section;

a plurality of engagement members which are each adapted to be secured to tissue upon deployment into tissue;

a plurality of deployment members adapted to extend from the distal section of the elongated housing in a distal and radially outward direction, each of the deployment members being adapted to deploy at least one of the engagement members into the tissue proximate to the blood vessel such that the engagement members are secured to the tissue proximate to the blood vessel and disposed at a distance from each other in engaged contact with said tissue, without engaging a wall portion of the blood vessel;

a plurality of elongate flexible tension elements, each tension element being secured to at least one engagement member; and

a retraction member coupled in operative arrangement with the tension elements and adapted to apply axial tension to the tension elements and reduce the distance between the engagement members to a radially retracted state to close the passage in the tissue proximate to the blood vessel.

2. The vascular closure device according to claim 1, further comprising a locking member adapted to secure the tension elements relative to each other in the retracted state thereby creating a tissue lock.

3. The vascular closure device according to claim 1, wherein the deployment members are adapted to deploy the engagement members with the tissue proximate to the blood vessel at a predetermined radial distance from the distal end of the vascular closure device.

4. The vascular closure device according to claim 1, wherein the engagement members are adapted to mechanically capture the tissue proximate to the blood vessel.

5. The vascular closure device according to claim 1, wherein the engagement members are adapted to rotate, pivot or expand once in engaged connection with the tissue.

6. The vascular closure device according to claim 5, wherein the engagement members each comprise a hypotube section having an inclined sharpened end portion.

7. The vascular closure device according to claim 1, wherein the engagement members are adapted to engage with a fascia membrane of said tissue.

8. The vascular closure device according to claim 1, further comprising a radially expandable anvil member adapted to extend distally from the distal end of the elongated housing into an interior volume of the blood vessel while in a constrained state, be deployed within the interior volume of the blood vessel and thereafter provide a reference point in relation to the wall portion of the blood vessel, and wherein the deployment members are adapted to engage the engagement members with the tissue proximate to the blood vessel at a predetermined distance from anvil member.

9. The vascular closure device according to claim 8, wherein the anvil member comprises one of a balloon, a deployable disk, a deployable positioning feature or an anchoring plate.

10. The vascular closure device according to claim 1, wherein the elongate flexible tension members comprise sutures secured to the engagement members, and wherein the retraction member is adapted to retract the sutures toward a common position adjacent a surface of the tissue proximate the blood vessel in order to reduce the distance between the engagement members and associated tissue respectively engaged therewith.

11. The vascular closure device according to claim 10, wherein the sutures are formed of a biodegradable or bio-absorbable material.

12. The vascular closure device according to claim 1, wherein the engagement members are formed of a biodegradable or bio-absorbable material.

13. The vascular closure device according to claim 1, wherein the elongated housing further comprises a guidewire lumen allowing the vascular closure device to be advanced over a guidewire.

14. The vascular closure device according to claim 1, wherein the deployment members further comprise a spring-loaded portion adapted to project the engagement members into the tissue.

15. The vascular closure device according to claim 1, wherein the retraction member is adapted to apply a predetermined retraction force to the tension elements to thereby reduce the distance between the engagement members which have been secured to the tissue.

16. The vascular closure device according to claim 1, further comprising a tapered nosecone arranged at the distal end of the elongated housing.

17. The vascular closure device according to claim 1, further comprising a device positioning member which is adapted to be aligned by visual approximation with a longitudinal axis of the blood vessel prior to deploying the engagement member.

18. A vascular closure device for closing a passage through tissue proximate to a blood vessel, the vascular closure device comprising:

an elongated housing having a proximal end and a distal end, the distal end adapted to be proximate the tissue;

a first and a second engagement member releasably arranged with the elongated housing;

a deployment member arranged with the elongated housing and adapted to deploy the first and the second engagement member at a distance from each other in engaged contact with said tissue, without engaging a wall portion of the blood vessel; and

a retraction member arranged with the elongated housing and adapted to reduce the distance between the first and the second engagement member to close said passage.

19. The vascular closure device according to claim 18, wherein the first and the second engagement member are adapted to mechanically capture the tissue.

20. The vascular closure device according to claim 18, wherein the first and the second engagement member are adapted to engage with a fascia membrane of said tissue.

21. The vascular closure device according to claim 18, further comprising an anvil member adapted to provide a reference point in relation to the blood vessel, wherein the first and the second engagement member are adapted to engage with said tissue at a predetermined distance from anvil member.

22. The vascular closure device according to claim 21, wherein the anvil member is configured to provide an orientation in relation to the blood vessel.

23. The vascular closure device according to claim 18, further comprising a suture connected to the first and the second engagement member, wherein the retraction member is adapted to retract the suture to reduce the distance between the first and the second engagement member.

24. The vascular closure device according to claim 23 wherein the suture and a corresponding further suture is individually connected to the first and the second engagement member, respectively.

25. The vascular closure device according to claim 23, further comprising a locking member arranged with the elongated housing and adapted to maintain the suture in a retracted state, thereby creating a tissue lock.
